# 3  Skateboarder’s Dream  - Cartographic Hysteria     Melting
The horizontal beam is pivoted from an earthen wedge allowing it to touch the production port at its lower end and control the orientations of nine hinged leaves.  The mechanisms attached along the beam measure, block, and open the reader’s movements.  The participant’s mass and movement energize the machinery and extend its physical dimensions.  Visual passage through the leaves is formed by steel tubes, and sound is reflected through a flesh-colored steel resonator.
